Designing Optical Fibre Cable Routes By Mobile Laser Scanning

Modern communication infrastructure relies on OFC routes. While GPS can help map the obstacles, MLS is the key for immaculate results.

India is undertaking a major revamp of its communications infrastructure by laying over 100,000 kilometres of Optical Fibre Cable (OFC) across the country. AAM India’s task was to map 2,500 km of proposed OFC routes across 33 cities to allow the contractor to decide where to lay the trench. All trenching is along existing road corridors, mainly in urban and semi-urban environments. The contractors needed mapping data with 50 cm absolute and 10 cm relative accuracy across all OFC routes to prepare accurate As Built drawings. The resulting maps needed to define all visible objects within 50 m from the road centreline, ensuring telecom, utility assets and manhole covers were defined.
